Working with numeric dates in AVR for .NET

Working with dates is something many RPG programs do extensively. In the old days of AVR Classic, we used to have to use lots of data structures and other special-case code to format dates, convert dates. It was also quite challenging to do date arithmetic and perform other sophisticated date manipulations. AVR for .NET's *Date, *Time, and *TimeStamp help resolve all of these issues. However, many shops still store dates (and times) as numeric values in their database. This seems to preclude using some of .NET's really great date handling and manipulation. This article changes that and shows how to integrate your numeric date and time values with .NET's great date and time handling.
